Using the Partially Demineralized Allogene Implant in the Skull Construction for Defects of Bone Compensation in the Middle and Upper Facial Zone

Aim: the development of an allogenic implant of the cranial vault with an osteoinductive effect, and the evaluation of its clinical effectiveness for bony defects of the upper and middle facial zones compensation.

Material and methods: the clinical study included 39 patients with defects and deformations of the upper and middle zones of the facial skull; a partially demineralized implant of the cranial vault was used in their surgical treatment. In 5 patients, the implant was used to reconstruct fragments of the frontal and zygomatic bones, in 34 patients – to restore the orbital walls late after the trauma, with atrophic changes present in the paraorbital tissues.

Results: The allogenic implant of the cranial vault obtained in a way as described above fit all the requirements for the demineralized bone matrix, it was easily modeled according to the defect shape directly during the surgical intervention. The obtained results were considered satisfactory.

Key words: demineralized allogenic implant, cranial vault, defects of facial bones, defects of orbital bones.
